title: Flunarizinium hydrogen maleate.
abstract: In the cation of the title salt {systematic name: 4-[bis-(4-fluoro-phen-yl)meth-yl]-1-[(2E)-3-phenyl-prop-2-en-1-yl]piperazin-1-ium hydrogen maleate}, C26H27F2N2 (+)·C4H3O4 (-), the protonated piperazine ring is in a chair conformation. The dihedral angle between the 4-fluoro-phenyl rings is 68.2 (2)°. An intra-molecular O-H⋯O hydrogen bond occurs in the anion. In the crystal, N-H⋯O, C-H⋯O and C-H⋯F inter-actions are observed, which link the ions into [001] chains.
